Comparative leaf micromorphoanatomy of Vitis vinifera SSP.vinifera (Vitaceae) r...

Aiming to characterize and discriminate between four red grapevine cultivars – ‘Aragonez’ (AR), ‘Cabernet Sauvignon’ (CS), ‘Syrah’ (SY) and ‘Touriga Nacional’ (TN) – grown under Mediterranean field conditions, we studied their leaf micromorphoanatomic characteristics under light (LM) and scanning electron microscopy (SEM). The studied characteristics included those of the epidermis, stomata and hair distributio...

Effect of chaetomellic acid on hematocrit, urine specific gravity and urinary v...

Chaetomellic acid (CA) is a potent and highly specific inhibitor of ras farnesyl-protein transferase that seems to reduce both functional and histological damage in uninephrectomized rats subjected to renal ischaemia-reperfusion injury. The aim of this work was to evaluate the effect of chronic treatment with CA on hematocrit, urine specific gravity and urinary volume in a model of renal mass reduction. Male Wi...

Cytotoxic effects of native and recombinant frutalin, a plant galactose-binding...

Frutalin is the α-D-galactose-binding lectin isolated from breadfruit seeds. Frutalin was obtained from two different sources: native frutalin was purified from its natural origin, and recombinant frutalin was produced and purified from Pichia pastoris. This work aimed to study and compare the effect of native and recombinant frutalin on HeLa cervical cancer cells proliferation and apoptosis. Furthermore, the i...

The effect of bovine milk lactoferrin on human breast cancer cell lines

The evidence that biologically active food components are key environmental factors affecting the incidence of many chronic diseases is overwhelming. However, the full extent of such components in our diet is unknown, as well as our understanding of their mechanisms of action. Beyond their interaction with the gut and intestinal immune functions, more benefits are being tested for whey proteins such as lactofer...

Flow of red blood cells in capillary networks

In the present work we have studied the flow of red blood cells through a column packed with soda lime glass spheres with diameter of 337.5 micron (pore diameter 150 micron). The ratio between the average velocity of the RBCs and the average velocity of the carrying fluid (physiological saline) was close to 0.9. The RBCs migrated faster through the column than the carrying fluid mainly due to a hydrodynamic chr...

Profilaxia para úlcera de estresse nas unidades de terapia intensiva : estudo o...

JUSTIFICATIVA E OBJETIVOS: O sangramento digestivo por úlcera de estresse (SDUE) é uma complicação grave dos pacientes criticamente doentes e com necessidade de profilaxia baseada em critérios literários definidos. O objetivo deste estudo foi revisar o uso de profilaxia para SDUE em UTI do Estado do Rio Grande2006do Sul, comparando os resultados com as evidências atuais da literatura. MÉTODO: Estudo transversal...

Obesity and the kidney.

Obesity represents an important risk factor for the development of chronic kidney disease (CKD), due to its known strong association with diabetes mellitus and hypertension, the two major causes of CKD, but also as an independent renal risk factor. This direct relationship between obesity and kidney injury has been undervalued. The aim of this revisión is to point out the mechanisms of kidney injury induced by ...
